Re: [HCDX] 657 KHZ Ticking
Hi,
thanks to Roberto, the ticking is apparently a night-time mode for the RAI transmitters in Italy. Most of them are usually on the air only from 0500 to 2300, with the exception of 24/7 Napoli-657 and Milano-900 which continue with the Notturno programme. Last night, also the others remained on the air with the ticking signal. On 657, there are also transmitters in Bolzano and Pisa (25 and 55 kW, resp., per WRTH 2011) which can be the source of the ticking, while Napoli continued with the regular RAI programming that I heard in the background.
The ticking was also strong on 1116 kHz, and here it was interrupted every now and then by normal Italian-language programming for a few seconds; a faulty audio feed connection might be the reason for the jumping between RAI and ticks, but this gives us quite a clue as to the origin of the ticks. On 1116, there are transmitters in Cuneo (20 kW), Palermo (10 kW) and smaller ones in Bari and Aosta. For my location in Germany, the signals probably comes from Cuneo in northern Italy. I also heard the ticks on 999 kHz with a slight delay (far less than 1 second) from the txers in Perugia, Rimini, Torino, and Vibo Valentia. The delay made the 400 Hz tones sound almost like Morse code.
It is quite a thing the 657 ticks made it all the way to Pennsylvania, congrats to RAI on your log! But how did they get on 500 kHz?? There are two UNID offshore beacons LGT and MCR on 500 kHz, presumably off the coast of North Africa (Libyan oil rigs?), as reported by NDB enthusiasts on http://www.classaxe.com/dx/ndb/rww/ but never reported in North America, and those beacons are not usually ticking either.
Have to check that... next night.
